Be sure to look up at the sky on Tuesday.
The moon will turn bloody red this Tuesday when it aligns with the Earth and the sun in the first central total eclipse in seven years, according to Discovery Channel.
The extraordinary event starts at 5:52 p.m.
“This is a rare occurrence as the moon usually passes above or below the imaginary line connecting the earth and the sun,” the popular cable network said in a statement.
During such an eclipse, the full moon will take on a dark red color as it will be illuminated slightly by sunlight passing through the Earth’s atmosphere.  This condition is also called the Blood Moon eclipse.
Discovery Channel said the moon would be at its “deepest red” for some 30 to 45 minutes.
The network said the brightness of the moon could vary greatly from eclipse to eclipse. “It depends on the amount of dust and clouds in the Earth’s atmosphere since these can block some of the refracted sunlight.”
“If you could watch an eclipse from the surface of the moon, your surroundings would grow dark as the sun disappears behind Earth. But the ground would still be lit by a red glow,” Discovery explained.
And looking up, one would see the source of the light – a glowing red ring around the Earth.
“The red ring is due to sunlight being refracted through the Earth’s atmosphere; the refracted light has the blue component preferentially scattered out (this is also why the sky appears blue from the surface of the Earth), leaving a faint reddish light to illuminate the Moon during the eclipse. It is the reason why the moon is not black but reddish during a total lunar eclipse,” Discovery said.
All phases of the eclipse will be visible from the islands of the Pacific Ocean, New Zealand and eastern Australia.
The network said the various stages of the eclipse would be in progress at moonrise for eastern Asia while the penumbral phase of the eclipse would start at about 3.53 p.m. “But most observers will not be able to visually detect the shadow until about 4.30 p.m. All of North America will witness some portion of the eclipse, but western observers are favored,” the Discover Channel added.
The early penumbral or umbral phases will be in progress at moonset. For observers in Maritime Canada, the moon sets in total eclipse from the eastern United States, the Great Lakes region and Ontario.  The entire event will be witnessed by those west of the Rockies, including Alaska.
Discovery Channel will be featuring a live video stream of the Blood Moon lunar eclipse on its Southeast Asia, Taiwan, and Australia/New Zealand sites from 5:30-8:30 p.m. (Singapore and Hong Kong time) on Aug. 28.  Sheila Crisostomo
